I did a remote ping to audio1.radioreference.com from my webserver just to make sure it wasn't my connection. Same thing, ping timeout. audio6 pinged back good though. I think I've always been on audio1... I've always ran tags with my feed as well if that makes any difference.

Open a port (port forwarding) on you computer. Then on scannercast config tab click on it and you will see SERVER. Enter a stream name, enter description and the port that you opened, place that in the server port, make the Max connections 0 and click on start broadcast. follow the instructions on scannercast's website.
